私はコーディングに不慣れで、誰かが私を助けてくれるかどうか疑問に思っていました。初めてWebサービスを利用しています。ただし、アレイへのアクセスに問題があります。何も出せない。
これで、Webサービスから情報を正常に取得し、NSArrayに保存できます。NSLogを実行すると、コンソールにコンテンツが表示されます。配列の数を確認すると5です。
しかし、どのコンテンツにもアクセスできません。エラー状態：CustomTableView [4083：11303]-[__ NSCFDictionary objectAtIndex：]：認識されないセレクターがインスタンス0xff231b0に送信されました
配列内のさまざまな値にアクセスする方法を本当に知りたいだけです。よろしくお願いします！:)
